为了建立一种基于镁热还原低氯化钛（低卤化物还原法）的快速/（半）连续制钛新工艺，研究了在1273 K下由四氯化钛（TiCl 4）与金属钛反应制备低氯化钛（TiClx，x=2，3）的新工艺。结果表明，以熔盐为反应介质时，TiCl_4的生成效率明显高于TiCl_4气体与固体钛直接反应时的生成效率。论证了TiClxin熔盐富集工艺的可行性。本研究所研究的低氯化钛生产方法可应用于钛的高速生产新工艺。
In order to establish a new high-speed/(semi-)continuous titanium production process based on the magnesiothermic reduction of titanium subchlorides (subhalide reduction process), a novel synthetic process for obtaining titanium subchlorides (TiClx, x=2, 3) by the reaction of titanium tetrachloride (TiCl4) with titanium metal at 1273K was investigated. It was demonstrated that the efficiency of the TiClxformation improved drastically when molten salts were used as the reaction medium as compared with that of the synthesis by employing the direct reaction of TiCl4gas with solid titanium. The feasibility of the enrichment process of TiClxin molten salt was also demonstrated. The method for producing the titanium subchlorides investigated in this study can be applied to the new high-speed production process of titanium.
